Velkoz/Thresh SuperKnockup

Though I didn't get it recorded, I'm pretty sure I know what happened. An enemy hooked my champion, . At roughly the same time, I used my "e" (knockup) somewhere between us. As reactivated his "q", the time delay on my "e" went off just perfectly. started coming toward me and as he was 1/2 way to me, he was knocked up by my "e". As a result, was knocked so high in the air that we couldn't see him. He as knocked up for a long time, maybe 3 seconds. When he came back down, he had very little life. I don't know if he was getting damaged while up or if we had just gotten his life down a lot. It was very clearly a bug, and something that shouldn't be happening.

This was in a ranked game and I was using League of Legends 4.19.14_11_05_21_19.
